Kingdom is the largest division that a group of organisms can belong to, for example “animal” or “plant” is a kingdom. In order: kingdom, class, genus, species.
Example of:
Class- Mammals would be a class of the kingdom “animal”
Genus- Homo would be a genus of “mammal”
Species- Homo Sapiens
Answer: the factors that increase cardiac output include:
--> Nervous stimulation and
--> Hypertrophy of the heart.
Explanation:
Cardiac output can be defined as the quantity of blood pumped into the aorta each minute by the heart. This is also the quantity of blood that flows through the circulation. There are factors that can cause increased cardiac output or that can lead to a hypereffective heart. They are:
--> NERVOUS STIMULATION: The combination of sympathetic stimulation and parasympathetic inhibition does two things to increase the pumping effectiveness or cardiac output of the heart. These include:
• it greatly increase the heart rate from the normal level of 72 beats/mum up to 180 to 200 beats /mom.
• it increases the strength of heart contraction, which is called increased contractility to twice it's normal strength.
--> HYPERTROPHY OF THE HEART: A long term increased workload, but not so much excess load that it damages the heart, causes the heart muscle to increase in mass and contractile strength in the same way that heavy exercise causes skeletal muscles to hypertrophy. This effect of increased muscle mass of the heart, allows the heart to pump much greater than usual amounts of cardiac output.
Answer:
Motor protein kinesin can "walk" along a microtubule while carrying vesicles and by changing its shape the kinesin.
Explanation:
Motor protein kinesin is an important microtubule based motor protein that is conserved among all eukaryotic organisms. Its movement along the microtubule is ATP powered. Most of the kinesins walk towards the plus end of the microtubule.
Due to its ability it is responsible for unidirectional transportation of cargos including membranous organelles and mRNA.
The given question is missing the chart or the details of blocks, each week. However, the details of the blocks are as follows:
1week = 2blocks
2weeks = 3blocks
3weeks = 5blocks
4weeks = 4 blocks
5weeks = 5blocks
Oweeks = 5blocks
7 weeks = 3blocks
Answer:
The correct answer is - 13.5 cm.
Explanation:
According to the details of the blocks, the number of blocks each week as follows:
1week = 2blocks
2weeks = 3blocks
3weeks = 5blocks
4weeks = 4 blocks
5weeks = 5blocks
Oweeks = 5blocks
7 weeks = 3blocks
Adding total blocks would be :
2 +3 + 5 + 4 + 5 +5 + 3 = 27 blocks
Each block equals 5 mm of growth.
Then, 27 x 5 = 135 mm
135mm = 13.5 cm
Thus, the correct answer is : 13.5 cm
